Ⅳ
. Setup of Welding Speed
The welding speed affects the welding quality and efficiency. Higher welding speed means less
gas-protection, accelerated cooling speed, lower flexibility and forming of welding seam. Lower welding
speed is likely to cause burning through of the workpiece and a puffy welding seam. In the actual production,
please keep the welding speed less than 30m/h.
Ⅴ
. Setup of Dry Extension ofWeldingWire
A longer dry extension of welding wire means a deeper penetration, a faster melting of welding wire and a
higher production efficiency. But an excessive length of dry extension is likely to cause burnout of wire and
splash of droplet. So a 10 times length of the welding wire diameter is always chosen in the actual welding
operation.
Ⅵ
. Setup of CO2 Flow
The CO
2
flow is rated to the gas protection effect. Besides, the gas protection of inside fillet welding is better
than that of outside fillet welding. So a lower gas flow shall be chosen. For specific digits, please consult the
form below.

Ⅰ
.Work Environment.
(1) The environment should be dry and the air humidity didn’t exceed 90%.
(2) Temperature should be from -10
℃
to 40
℃
.
(3) Avoid welding under rain or hot sunshine, don’t let water or rain into machine.
(4) Don’t work under dust area or aggressive fume.
(5) Avoid using the machine under strong air flow.

. Safe tips.
The machine is equipped with overvoltage, overcurrent and overheat protection device. If the voltage, output
current
and temperature exceed the standard, the machine will stop working. Besides, overusing the machine based
